I just got a Mitsubishi BD2 dozer running again and was running great, then the 6 way blade started moving sluggish and then quit. Filter is new and hydraulic fluid is full and a little milky. If I let it set for 15 min it will move slow and then stop again. CausticUrbanCoast has been a life saver on these post. Thank you CausticUrbanCoast. He also asked is I checked the strainer. Where can I find the strainer and I will look.
